Question
Acid deposition is rain, snow, fog, or dew that contains higher than normal amounts of ______, which lower water pH in ecosystems.Multiple choice question.persistent organic pollutantssodium and phosphorussodium hydroxidessulfuric and nitric acids
Solution
The correct answer is sulfuric and nitric acids. Acid deposition, also known as acid rain, is primarily caused by emissions of sulfur dioxide and nitrogen oxides from industrial processes and combustion of fossil fuels. These gases react in the atmosphere with water, oxygen, and other chemicals to form sulfuric and nitric acids. These acids then mix with water and other materials before falling to the ground. This can lower the pH of water in ecosystems, making it more acidic.
